Hi!
To start with insane.. Things are being wide-spaced overall, and well. I see spacings to be this and that here and there. That is, I can't feel some constant spacing usage, and the current spacing usage didn't felt effective enough to represent the actual song. Take 00:10:204 (3,4,5,1) for example. (4,5,1) is having a same spacing, while (3,4) is having a small jump. The jump selection was kinda understandable since (4) is having a somewhat higher sound, but (1) which is having a stronger sound having no jump while the weaker sound of (4) having one was not fitting the song nicely imo.
The following stuff might be rather minor, but 01:09:750 (2,3,4) things like this. Visually, it has a somewhat similar feeling enough, but the spacing has a 0.1x difference. Pretty nazi you may think for "just" a 0.1x? But if minor stuff gathers and gathers... it becomes some unpolished setting afterall, which you could've worked yourself beforehand. Just in case if you insist that to be an intended setting, having such minor difference gives less spacing emphasis effect since we can't tell the visual difference significantly. But it is actually inconsistent, so it is called a spacing inconsistency.
Also some consistency issue present. 00:11:113 (1,2,3) and 00:12:931 (1,2,3) are pretty much similar enough, but are expressed as a totally different pattern. Like, the close spacing of 00:11:113 (1,2) is not a usual setting considering how the overall spacing is expressed largely. And then when it comes to 00:14:750 (1,2,3), there is not much difference in rhythm-wise while there is an additional beat at 00:14:977 unlike the previous two. Expressing similarly for similar part of the song and expressing differently for different part of the song is recommended. And this is a very basic idea of a structure.
And things like 00:36:568 (1,2,3,4,5), although I felt this to be consistently used through out the map, I'm not really sure the emphasis concept was thorough enough. (1,2) has a regular spacing, (2,3) has a jump, (3,4) has a regular spacing, (4,5) has a jump. And when listening to the actual song, it is (2) and (5) that is having the same sound while it was (3) and (5) that is containing a jump. Since you were placing emphasis inconsistently in the first place, it was really unclear what you wanted to emphasize.
Seeming from the combo settings, I feel 00:51:113 (1,1,2,3,1,2) - 02:23:841 (1,1,2,3,1,2) this kind of things to have some meaningful stuff inside your map. First of all, I've found the concept itself of a combo setting to be interesting enough. The stuff that wasn't really cool enough was the patterns. Even you were intending these to become something special, the patterns aren't really special and can't really tell the difference with other things if there were no new combo here. If you want to give some special meaning at a special part, you'll want to think more deeply than just adjusting the comboes.
The good part was the flows I guess. Despite several inconsistencies, I felt the flow itself working fine enough.
Hard felt fine enough. Just I didn't felt much technically impressive ones, but what you've done are already sufficient enough imo. Just to mention again, you'll want to avoid some meaningless spacing inconsistency such as 00:06:568 (3,4) - 00:59:750 (4,1) or 01:10:204 (3,4) etc.
Normal was just solid. Though several 1/2 objects didn't felt really beginenr friendly, I guess it could work as the lowest difficulty enough.. or maybe not. Some 1/2 in kiai section feels a little too much when considering the actual spread of this set. For example, 00:57:931 (3,1,2,3,4,1,2,3,4,1,2) could have some 1/1 interval. It's a little too dense atm.
Rating : 5 / 10 - could be a 6 enough after further polishment!
General.
-- 02:09:295 - Wouldn't starting the break from here will work better along the vocals?
-- 02:23:841 - While other similar sections are having a red-white combo color combination, why is this section having a brown-red combination? I honestly feel this part of the song have no difference with 00:51:113 or 02:38:386. Setting a different color while there was no musical difference felt like a huge inconsistency.
Normal.
00:47:477 (1,1) - 02:03:841 (1,1) - 02:22:022 (1,1) - You'll want a longer spinner recovery time. "But this is a normal" won't work too much, since this is technically the lowest difficulty in the mapset afterall.
Hard.
02:38:841 (1,2,3) - 02:39:750 (1,2,3) - (2,3) is notably closer than (1,2). Considering your previous similar parts, it felt highly inconsistent. If this was an intended behaviour, you'll want to make things even consistent with 00:51:113 (1,1,2,3) etc since previous ones had no noticable difference. Variation doesn't work enough imo since the pattern is really different while the song is pretty similar enough. Rather a variation worked better at 02:57:022 (1,2,3,1,2,3) since the music was clearly different. And that pattern is consistent with 02:38:841 (1,2,3) while the music is different..? Structure issue.
02:29:522 - 02:29:977 - These are containing clear vocal lines. Leaving this empty felt a little missing.
Insane.
00:14:750 (1,2,3) - The stack in-game doesn't looks good enough here. You'll want to use some manual stack.
01:00:204 (1,2,3,4) - How is these sliders created? I smell this to be a zigzag slider based on mirrored form, but when checking individual sliders each, I only end up seeing multiple directions that are all different.
